Working on the low-chilling apple cultivar ?Eva? grown in mild winter conditions of southern Brazil,
we studied the influence of bud position along the one-year-old shoot on dormancy release and water
content during winter, and actual budburst in spring. Firstly, during winter, the water content measured
in planta increased, and the mean time to budburst measured ex planta with the single-node cutting test
decreased, for buds from the distal half of shoots whereas such trends were not observed for buds in
the proximal half. These two phenomena revealed a higher growth capacity of distal buds during winter
compared to proximal buds. Secondly, at spring, there was an acrotonic budburst pattern similar to that
of high-chilling cultivars grown under cold winter conditions. We discuss the interest of these winter
bud traits as reliable markers of the adaptation of low-chilling apple cultivar to mild winter conditions. |
